Benefits of technology

[0008]Therefore, an object of the present invention is to provide an image processing program and an image processing apparatus capable of detecting a contour of an image of a three-dimensional space with a stable load while preventing the processing load from excessively increasing, depending on the situation.

Problems solved by technology

Therefore, the larger the number of polygons constituting one model, the more the processing load.
Also, the larger the number of models to be drawn, the more the processing load.
Therefore, if the distance from a camera to the model is large, the outline may be too thin to be visually recognized.
Conversely, if the distance is excessively small, the outline may be excessively thick.

Abstract

A game apparatus generates an image of a three-dimensional virtual space as viewed from a predetermined viewpoint, an object being provided in the three-dimensional virtual space. Next, the game apparatus obtains a depth value (Z value) indicating a depth from the viewpoint in a line-of-sight direction in the three-dimensional virtual space for each pixel of the image. Further, the game apparatus detects a pixel corresponding to a contour of the object based on the depth value. Specifically, a plurality of pixels are specified as reference pixels. It is determined whether or not a pixel of interest corresponds to a contour, based on a change level of differences in depth value between the pixel of interest and the reference pixels.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The disclosure of Japanese Patent Application No. 2007-154114, filed Jun. 11, 2007, is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an image processing program and an image processing apparatus. More particularly, the present invention relates to an image processing program and an image processing apparatus for executing image processing to generate an image of a three-dimensional virtual space.[0004]2. Description of the Background Art[0005]Conventionally, in order to generate a cartoon-like (comic-like) image by three-dimensional image processing, a process of drawing an outline (contour) of a model formed of polygons has been proposed. For example, in image processing apparatuses described in Patent Documents (Japanese Patent Laid-Open Publications Nos. 2000-251094, 2001-126086 and 2001-084404), a model indicating a character or the like (basic model) a...
